Landscape Mysteries - Secrets of the Flood

Professor Aubrey Manning collects evidence of a flooded landscape beneath the Solent and of raised rock arches in Scotland, cut by coastal erosion, but now high above the sea. The explanation is the land movements that have occurred since the melting of the huge layers of ice that were centred on Scotland more than 8,000 years ago. As the weight of ice over Scotland was reduced, the land rose. The UK effectively tilted and southern Britain sank slowly into the sea. The effect is still going on and Antony Long from the Environment Research Centre is one of those involved in vital work to gauge the advancing sea levels and decide on the best response. As the sea encroaches over low lying areas of southern Britain, the main question is whether to build ever bigger barriers or simply to allow the advance to progess naturally, with the accomanying salt marsh forming its own barrier.
